Abstract
Background: Devices fabricated on flexible substrates find diverse applications. The advancement of materials and manufacturing methods is critical for improving flexible devices. Method: This study compares ultrafast Ar and O2 microwave plasma (MP) treatments in terms of their high energy efficiency and high ionization rate to process solvothermally grown NiCo-metalorganic frameworks (NiCo-MOFs) on flexible carbon paper (CP) substrates. Significant Findings: Ar MP treatment reduces the oxidation states to reveal metallic states, whereas O2 MP treatment enhances the oxidation effect with no apparent metallic reduction. Samples treated with Ar MP become less hydrophilic whereas those treated with O2 MP retain the hydrophilicity of pristine NiCo-MOFs. The oxidation capability of O2 MP and reduction capability of Ar MP treatments can be beneficial for general materials processing.
